    GitLab Community and Enterprise Editions Remote Code Execution Vulnerability — GitHub Community and Enterprise Editions that utilize the ability to upload images through GitLab Workhorse are vulnerable to remote code execution. Workhorse passes image file extensions through ExifTool, which improperly validates the image files. Listed in the CISA KEV catalog (added 2021-11-03) — confirmed exploited in the wild, not theoretical. It is linked to known ransomware campaigns. FIRST EPSS puts the chance of exploitation in the next 30 days at ~100%. Treat it as real and prioritize remediation over triage.

    Remediation · TruePositive EditorialCurated

    Required action for GitLab Community and Enterprise Editions: Apply updates per vendor instructions. CISA set a federal remediation due date of 2021-11-17. After patching, verify the vulnerable path is no longer reachable before closing the finding.
